Application filed August 18,1913. "serial no. 785,289.

To all 'whom it may concern Be it known that I, EDWARD F. RESGHKE,citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Nipples, of which the following is a specification.

This invention relates to improvements in the class of nursery devicesknown as babycomforters which comprise a rubber nipple with suitablemeans by which it can be used without danger of being swallowed by theinfant. My improvements are also applicable to nipples used with nursingbottles.

In devices of the type to which my invention belongs, the teethinginfant, by biting upon the thin walls at the neck or base of the bulb,cause holes which destroy the elficiency of a nursing nipple. In somecasesy teething infants have been known to bite the nursing or comforternipple in two and choke upon the severed bulb portion.

In baby-comforters of commerce, it is customary to combine a teethingring with the nipple.

My invention is designed to avoid the objections above mentioned and to`render the teething ring superfluous. In the accompanying drawing I haveillustrated preferred and modified embodiments uof my invention in thefollowing views:

Figure l shows a baby-comforter constructed in accordance with myinvention.

Fig. 2 is an enlarged view, partly sectionized of my improvedbaby-comforter; and Fig. 3 is a vertical section through a nursingnipple arranged upon the stopper of a bottle, the mouth only of thelatter being shown. Figs. 4 and 5 show a slightly modifled form of myinvention.

i Referring to the details of the drawing, the reference character 4represents the bulb portion of a rubber nipple,-the walls of which aremade thin at the point and gradually increase in thickness toward theneck or base of the nipple, as clearly shown in Fig. 2.

5 represents annular corrugations formed in the walls of the baseportion of the nipple, which are materially increased in thickness atthis portion. The surface ofthe corrugations is roughened by serrationswhich preferably extend diagonally of said corrugations and in oppositedirections.

The usual disk or guard is shown by the reference numeral 6, and 7represents the nipple holder or attachment, the latter being formed witha stem 7 a which is adapted to fit within the base of the nipple and isgiven a bulbous form to prevent the too easy withdrawal of the nipple.The outer portion of the holder is provided with a hole 7b, throughwhich a cord 8 is strung, the latter serving to provide suitable meansfor attaching the device to the infants person or garments.

The holder 7 is formed of bone, celluloid, vulcanized rubber or othernonyielding substance so that the stem 7a affords an unyielding backingfor the base portion of the nipple, and thus combines with thecorrugations 5 in providing the desired resistance which willVfacilitate the cutting of :the infants teeth. This action is furtheraugmented by the serrated surface of the corrugations.

Fig. 3 shows my improved nipple applied to a bottle stopper having thesame functions as the comforter shown in Figs. 1 and 2. In said Fig. 3,the reference numeral 9 represents a nursing nipple, 9n the corrugatednipple base, l0EL bottle stopper having a perforated stem l0 whichenters the nipple and 10b the guard, which, though not required with abottle nipple, is shown as a means of limiting the entrance of thenipple to the infants mouth and thus serving to confine the bitingaction to the corrugations adjacent the guard.

In Figs. 4: and 5, I have shown the thickened and serrated walls at theneck portion of the nipple instead of at the base or open end, the samebeing indicated by the reference character 5b.

I am aware that nipples have been made with thickened walls at theeXtreme end of their mouth to increase their gripping action upon thebottle neck or other` holder, but, so far as I am aware, these thickenedportionsw are not accessible to the infants gums, while my inventioncontemplates the formation of the c orrugations at such porjacent thebulb portion having thick and 10 tions of the nipple as may be readilyreexternally roughened walls.

Having thus described my invention", what EDWARD F' RESCHKE' I claim asnew is: Witnesses:
